What kind of rail, what kind of bearings?

Sorry for the late reply everyone.
This is the machine I bought:
[www.banggood.com]
The rails are 0.5" rods. The bearing housings are the through hole type. The whole thing is made and aluminum and it's heavy. I know that the bearings are to be tight to eliminate play while cutting, but they bind to much. The movement isn't smooth at all. It uses NEMA17 steppers.

Machine is fully built and I nailed it getting to move smoothly. The spacers worked great. Took some time to get it done but it's together tight and moves smoothly.

Is it a problem on all axis, maybe the bolts need to be tightened in diagonal pairs, maybe loosen(or check) rails.

Cool, I don't know about the new machines. It seems every machine has it's own quirks. I have only done DIY machines so far. And I got an old 3D-printer, a Replicator 2x that had pretty bad bushings on it that I fixed and now it runs smoother than ever.
I guess it's all down to the user to make sure it works. Share some of your first work when it's done, I'm curious what this machine can do!

The Chicom 3D printers have a flexible frame that prevents to some degree, the bearings from binding too much. They are just noisy, the time it takes to grind the guides enough.
Here, the frame seems sturdier, therefore binding is as normal as the poor alignment. It is cheap, isn't ? 0.5" diam is quite strange, not standard, is it US made ?
Check if the rods are hardened steel, not soft stainless. In SS, better plan their replacement.

I got my Red 1419 CNC router cutting. Works great. I had an issue with the z-stepper it came with and the z-stepper replacement I purchased, but I fixed the replacement and its working great.

Exactly. This is literally my first CNC cutter so i purposefully ran it really slow because I didn't know how the machine was going to behave. I ran it super slow and even though I thought I was only cutting a tiny bit, in height per pass, it was still a little bit to much. I'm trying to dial in the distance per revolution now.
